Summary
A rare case of primary osteogenic sarcoma in the retroperitoneal space was successfully treated. Combined chemotherapy (cyclophosphamide, vincristine, adriamycin, and dimethyl triazeno-imidazole carboxamide) following surgery led to a positive outcome.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Primary osteogenic sarcoma typically arises in bone.
- Extraosseous osteogenic sarcoma (ESOS) in the retroperitoneal space is exceptionally rare, with limited reported cases.
Observation:
- A 33-year-old male presented with left flank pain.
- A large retroperitoneal tumor was identified and surgically resected.
Findings:
- The resected tumor was diagnosed as primary osteogenic sarcoma.
- Post-operative treatment with cyclophosphamide, vincristine, adriamycin, and dimethyl triazeno-imidazole carboxamide (CYVADIC) chemotherapy resulted in no recurrence for over ten months.
Implications:
- This case highlights the potential efficacy of combined chemotherapy and radical surgery for ESOS.
- Aggressive multimodal treatment may improve survival and offer a possibility of cure for this rare malignancy.
